Hello, newbie here.. traded for a 69 cloned z28 had a t400 that previous owner swaped out a muncie 4speed ..very poorly i might add.. so it didnt live long.. bout 4 miles. 😡.. anywho.. i put a tko600 5 speed in it and would like to convert the auto column to a Manuel column. . Since it is a tilt already.. I'd like to keep it.. is there anyone who could just rebuild and update the one i have..?? Thanks for any help.. !! Alex R
